Router metrics can include any number of values that assist the router in selecting the most advantageous path out of several options to a destination.

Usually based on data about path length, bandwidth, load, hop count, path cost, delay, MTU, dependability, and communications cost, a router metric measures how well a router performs. Finding the optimum route to take when sending packets is a router's main duty. The router looks through its routing table for a network address that corresponds to the packet's destination IP address in order to find the optimum route. To find the best path to a destination, OSPF employs a cost metric that represents the state of the link and the interface's bandwidth in an algorithm. The SPF (shortest path first) or algorithm is the one that is employed.

The broadcast ARP message is sent to all the nodes on a particular network to get the MAC addresses of those all nodes and maintains a Cache table with all the IP addresses and MAC addresses of all the nodes present in that network.

What is the difference between a MAC address and an IP address?

The manufacturer of the hardware interface assigns the MAC address, whereas the network administrator or Internet service provider assigns the IP address (ISP).

The IP address is an address that enables you to recognize a network connection, whereas the MAC address is a specific hardware identification number that is assigned to a NIC (Network Interface Controller/Card).

IP address describes how the devices are connected to the network, whereas Mac address specifies the identity of the device.

Hence ARP protocol is very important , Because at the end ,all the IP addresses needs to be converted into MAC address to send the packets to exact destination computer.

Random numbers appear in a given distribution only when two conditions are met: Values are evenly distributed over a given interval or series, and it is impossible to predict future values based on past or present.
